Specification forming part of Letters Patent No. 5.067, dated April 17,1347.4

'loenable others skilled in the art to make j and use my inventiom I will proceed tc describe its' construction and operation.- Y I construct my frame "in'ay form suitable to the machinery to be used, which machinery l shall now describe as presented in Figure l of the accompanying' drawings. y A is the steam-cylinder; B, piston-rod; C C, levers working in journals at z z,- D vD,l

'equidistanttriangles working n pon journals at w m; F F, arms connecting levers C C with piston-rod B at o o; G G, arms connecting` levers G'with triangles D Dat y y; H YH, arms connecting triangles D D with the platen at r n; L, double valve for the admission and' escapement of steam; E, the platen; K, beam -on whichA the cylinder stands. y

The bale of cotton is placed upon the platen E. Steam is then introduced. to thehylinder Aat'the valve L,4which Vforces-the piston-rod B to ascend, drawing with 'it the levers G C by means of the connecting-arms F F, and the triangles D D, being connected with arms C C at au by the arms G G, arefforced up, turning upontheir journals at x a3, and the platen E, being attached to the triangles D D at w yw by-means ofthe arms H H, rises perpendicularly, 4and thus presses the bale between itself and the beamlv When the bale is tied, the steam is letoi' :at Valve L, and the resistance of the bale causes the' machinery to descend, and its vowirweight carries it to its original position. The triangles lare double, as at d (Z,

2, so that thev arms G'G, lwhen the niaehinery is in operation, pass between the arms H I-I. These triangular levers 'operate in the first instance as levers of the third.- order until the .arms G G pass the' joints of the arms H H at w 1r; when 'they assume the chan acter of levers of the seconder-der, and then lcommences theA increase of power, and it is only then that the resistance of the bale commences, for'the space between the platen E` and the beam vKis four feet six inches. Theactual size of the' bale when first introduced is about three feet, so thatl the platen moves up about eighteen inches before there is any resistance. -It then continues up eighteen inches farther, when itv ceases to operate, l making its Whole upward, movement three feet, fvvhichz` leaves the bale when pressed eighteen inches. The increase of power is rapid so soon as the` trianoles assume the second. order of 'lever-z b power, and then only 1s it required.

What I claim as my invention, and desire to.'

secure by Letters Patent, is-

'The 'application of equilateral triangular levers, (D l), as per drawings,) in combination with ordinary levers ofthe second order, (C C, as per drawings,)`the latter to be'opery ated upon by direct application of steam-pow' er, for the purpose of compressing cottonbales insuch a :manner that the increase of power by means oi' thecombination shallibe equal to the increased resistance of the bale of cotton undergoing the pressure necessary to reduce it to as small a compass as. may vbe required. y L 1 l refer to the drawings now in possession of theDepa'rtment and to the specification' above,
